Hi.
There is an old issue (https://www.illumos.org/issues/263):
useradd -m tries to create home directory under /home, but /home is
auto-mounted
from /export/home.
For useradd -m to work, you should specify useradd -m -b /export/home
..., but
users created in such way are not equivalent to initial user, which
we get on
install, as for them mapping in /etc/auto_home is not created.
OI /dev had several patches to fix this:
https://github.com/illumos/illumos-gate/commit/d6271a348bada25d0a512551be0ae6a9aa334d84
(263 useradd is unable to create home directory)
and
https://github.com/illumos/illumos-gate/commit/70501a0c9a45806dbe4a81c2195b2647fa982f79
( 288 New homedirs should have auto_home entries)
I think that these patches are too specific to be accepted in
illumos-gate.
What can we do with it? Perhaps we just remove all auto_home magic by
default
and create home directories under /export/home ?
We also could set something like
* localhost:/export/home/&
in /etc/auto_home, but IIRC this leads to the following : if you try
to access
/home/bar you'll receive irritating error messages on console about
missing
/export/home/bar.
As you said, it's too specific. Users using NFS mounted directories
for /home have wildly different setups (we alone had three completely
different approaches in a decade), they know what they do. So the
best option is to leave it as it is, either the admin uses the -b
option, or don't use the -m option at all since he creates that
directory by different measures.
Agree.
It's the wrong fix for the problem of useradd not working out of the box.
A better (and much simpler) fix would be for useradd to use /export/home
as the default for homedirs, which would make useradd on a new
stand-alone install just work.
If you want useradd to work with maps, it's going to need a ton more
smarts which aren't in it at the moment, and I bet people with
widespread use of maps still wouldn't use it, so I think there's little
point in that effort.
